SPECIFICATION forming part of Letters Patent No. 286,331, dated October9, 1883.

Application mea May 23, ross. (No model.)

To @ZZ whom, it may concern:

Be it known that I, BENJAMIN C. RICHARD- SON, of Detroit, in the countyof Wayne and State of Michigan, have invented certain new and usefulImprovements in Milk-Coolers; and I do hereby declare that thefollowingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, which formapart oi this specification, and in which-- Figure l is a verticalsection of my improved crea-ming-can. Fig. 2is a perspective view of therefrigerati-ing attachment removed from the milk-can, and Fig. 3 is avertical section of a modification of my invention.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of milk-coolers in which the'ice-receptacle is placed inside of the milk-can;r and it consists inthe improved construction and combination of parts of the same, ashereinafter more fully described and claimed.

In the accompanying drawings, A represents the body of the milk-can,inside of which rangement I keep the ice dry, so that it will therefrigerating attachment is placed. The can is provided at its upperpart, near the neck, with two or more air-tubes, B B, for allowing theanimal heat 'and gases arising from the milk to' escape from the can,the outer ends of the air-tubes being covered by screwthreaded caps B. Anumberof holes (shown at b) are pierced through the sides of thescrewcaps and the sides of the air-tubes, so that by turning thescrew-threaded caps vuntil the holes b in the caps and the holes c inthe airtubes register the animal heat and. gases arising from the milkmay escape from the can without removing the caps entirely from theair-tubes.

C is the ice-chamber ofthe removable cooling attachment, and isconnected by three or more tubes, D D D, to the drip-pan E. As the icein the chamber C gradually melts, the water runs down through the tubesD vinto the drip-pan E, where it is collected. By this arlast twice aslong as it would ifthe water were allowed to remain in the same chamberwith the ice. LBy constructing the cooling attachy ment-in the mannerdescribed, I succeed in cooling the milk in an exceedingly short periodof time. A cone-shaped stud, F, is attached to the inner surface of thebottom of the milk-can, and fits into a conical recess, F', in thebottom of the drip-pan, thereby holding the lower part of the coolingattachment iirmly in position. The cover of the milkcan. has an annularmetal strip or ilange, G, soldered or otherwise fastened to the innersurface of the cover, so that when the cover is placed upon the can theannular strip or flange G will fit tightly between` the outer surface ofthe ice-chamber and the neck of the can, which arrangement, togetherwith the cone-shaped stud F, fitting into the conicall recess inthebottoni of the drip -pan, will serve to hold-the cooling attachmentiirmly in position and prevent any displacement of the said cooler whenthe can is being roughly handled. On the outside of the ice-chamber,near its top, are two lugs or projecting pins, H H, adapted to fit intoslots I I in the annular strip G. vlll-Then lit is desired to remove thecooling attachment from the can, the cover is turnedvor rotated tothelcft, when the lugs or proj ecting pins H H will enter the slots I Iin the annular strip G, when the cooling attachment can be lifted out ofthe can by the handle of the cover.

Ii' desired, a small tube, J, may be inserted into thev bottom of thedrip-pan, the free end of the said tube passing through an opening inthe bottom of the can, said opening being provided with a washer ofsuitable material,

in order to make the opening water-tight when the tube J is passedthrough it. of the tube J is closed by a screw-threaded cap, J so thatby removing the said cap the water in the drip-pan can be drawnoffwithout removing the cooling attachment from the pan. The aboveconstruction is clearly illustrated in Fig. 3 of the drawings. When thetube J is used with my improved 'milk-cooler,

thelower rim of the can, on which the weight` of the can rests, is madeof a sufficient depth to keep the screw-cap on the tube from coming incontact with the ground.

From the foregoing description, taken in connection with theaccompanying drawings, the construction of my improved milk-cooler willreadily be understood. without requiring The free end I IOO extendedexplanation. It will be seen that my improved milk-cooler is simple inconstruction, and is very convenient to handle in removing the Waterfrom the cooler. .e

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- Y In a milla-cooler, thecombination of the receptacle A, provided with suitably-constructedvent-tubes and caps covering the same, coni-y caln'stud or projection F,located centrally in the bottom of the can, removable refrigeratingattachment composed of the ice-receptacle C, drain-tubes D,' and closeddrip-pan E, having conicall recess F', adapted to t the stud F, 1`5 vandcover having a downwardly-projecting iiange, G, adapted to iit betweenthe outside of the ice-receptacle and the neck of the can, the f wholeconstructed and combined substantially as and for the purpose shown anddescribed.

In testimony that I claim the foregoingas my oWn I have hereunto affixedmy signature in presence of two Witnesses.

BENJAMIN CLARK RICHARDSO.
